We celebrate Rosh HaShanah (the head of the year) based on two aspects.
On one hand, we thank the Creator for having made us exactly as we are and for determining everything concerning us precisely in this way. In doing so, we acknowledge His authority over us, as the King over the entire earth. This is one aspect of Rosh HaShanah, which is called “accepting the burden of the kingdom of heaven.” It concerns the initial, primordial qualities, (the gene and the ways of its development) embedded in a person. This is what takes place in the soul.
And on the other hand, we thank the Creator for leaving a major part of our development in our hands and for providing the opportunity to study His actions (“from Your actions we shall know You”) to reach an understanding of Him, to know Him, to draw closer to Him, to become similar to Him, and to attain adhesion with Him.
In essence, it is not important to us that we determine our fate, learn from Him how to perform corrections upon ourselves, and know by which path we need to come to correction. It is not even important to me whether I advance toward the final correction by a good, pleasant, short, and certain path or choose the closest path out of the two possible ones: the short path, or the long one.
What is important to me is that, by doing so, I thereby become similar to the Creator, and enter into adhesion with Him. This, in essence, is what it means to bring contentment to the Creator.
Thus, the celebration of Rosh HaShanah has two meanings for us. On the one hand, the Creator brings us into existence with those inner qualities that He determines. This means that He rules over us. On the other hand, He has also given us the opportunity to learn from Him how best to advance and to assume various correct forms according to our study and our own choice. As a result, we learn to become similar to Him and attain adhesion with Him.
All of this is contained in the holiday of Rosh HaShanah. That is why it is called the “head of the year.” Beyond this, there is nothing else left for a person to do. We now see that both in the material sphere, and afterward in the spiritual sphere—it does not matter whether we are in one of these dimensions or in both at the same time—such an attitude toward oneself and toward one’s surroundings, toward the world, essentially includes the entire process and all the forms through which a person passes.
